When the first connecting rod 403b and the second connecting rod 403c are located in the same straight line direction, the front end of the sliding rod 501 abuts against the arc surface and is pushed outward by the arc surface. When the second connecting rod 403c rotates, the sliding rod 501 is free from the obstruction of the arc surface. At this time, the spring 503 will pull the sliding rod 501 to move upward, thereby pulling the rotating ring to move into the adjusting wheel 302a.

[0071] Operation process: when it is necessary to grab the user's pants, the telescopic seat cushion is extended, and the side panel 301a connected thereto is synchronously driven to extend outward, so that this side panel 301a is close to the user's pants position. After abutting, the electric cylinder 403a in the side panel 301a is started to push the first connecting rod 403b outward. After pushing, because the first connecting rod 403b and the second connecting rod 403c are in a hinged state, when the first connecting rod 403b slides out of the storage groove 404, the second connecting rod 403c is driven by the torsion spring 403d to rotate toward the pants direction. At this time, the adjusting wheel 302a is rotated from the state of abutting the pants from the side to the state of abutting the pants from the end side. At this time, the position of this side panel 301a is fixed. At this time, the user's pants are adhered by the adhesive layer on the abutting bottom plate 402e, so that the side panel 301a is rotated in the opposite direction to take off the pants.

[0072] The two states of the adjusting wheel 302a (abutting against the pants on the side or against the pants on the end side) enable the adjusting wheel 302a to be transformed into abutting against the pants on the end side and grab the pants when going to the toilet or other actions are required. When only the retractable seat cushion needs to be extended but the pants do not need to be held, the sides of the two adjusting wheels 302a abut against the pants, and the abutting bottom plate 402e on the end side of the adjusting wheel 302a will not be used to grab the pants, making the entire device more user-friendly.
